Tired of Unpredictable Electrical Problems in Your Truck?

When features like your power windows, door locks, interior lights, or even the HVAC system start acting up, the problem often points directly to a failing Body Control Module (BCM). This component is the central command center for your vehicle’s body electronics. Instead of dealing with intermittent failures or costly diagnostic fees at the dealership, take control with this direct-fit, VIN-programmed BCM.

An Expert’s Note on Installation
“Many owners don’t realize that a new BCM from the dealer is just a blank box. You still have to pay for labor to install it and then an additional programming fee to make it work. Our process handles the programming before we ship, using the latest GM software updates. This saves you hundreds of dollars and significant downtime. For a part this critical, ensuring it’s programmed correctly to the VIN is the most important step, and we take care of it for you.”

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, locks, lights, wipers, the security system, and the HVAC blower motor, ensuring all these comfort and convenience features function correctly.
Is this module truly plug-and-play?
Yes. We pre-program the module using the Vehicle Identification Number (VIN) you provide during checkout. This ensures it communicates perfectly with your truck’s other systems right out of the box, with no need for additional dealership programming.
What if my airbag light is on after installation?
In some cases, particularly if you have an active DTC B1001, the new BCM needs to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). This requires a professional scan tool to perform a ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync, not a full reprogramming.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module without any hassle or extra fees.
How do I know if this is the right part for my truck?
This 2011 Sierra Denali 3500 Body Control Module is compatible with a wide range of 2007-2013 GM trucks and SUVs. You can confirm fitment by matching your vehicle in the compatibility chart or by cross-referencing your original part number with the numbers listed in the description, such as 25844480, 15878753, or 25835966.
